Doc Text:
A flaw was found in the Linux kernel. A vulnerability in the `drm/amdgpu/gfx11` graphics driver could cause the system to crash. This issue arises from a condition that, when met, would trigger an error-handling mechanism designed to halt the kernel (BUG_ON()). An attacker with local access could potentially exploit this to cause a Denial of Service (DoS), rendering the system unusable. The fix replaces this critical error halt with a warning (WARN_ON()), preventing system instability.
